This is where information will be placed for the electronic speed control.

Rough Power Estimation This is a best guess for the max currents needed by the three main system voltages 36, 24,and 12V.

36V - 32.1A Total

• Motors and Driver 25A
• 24V DC-DC Converter 0.88A
• 12V DC-DC Converter 6.25A

24V 1.05A Total

• Sick Laser 0.8A
• Ethernet Hub 0.25A

12V - 20A Total

• CPU1 10A
• Other Electronics and Sensors 5A
• Dell 14" LCD Monitor - 3A

Preliminary Power Block Diagram

This is my best guess on the power consumption of the different components.

Possible 12V DC/DC Converters

• 12V, 12.5A $145.00
• Artesyn Technologies BXB150-24S12FLT
• CONV DC/DC 12VOUT 150W ACTIVE LO

Possib;e 24V DC/DC

• 24V, 2.08A $85.46
• CUI Inc, VHB50W-Q24-S24
• CONVERTER DC/DC 24V 2.08A 50W

info from Chris King: Hi Fred,

Here's the link to the voltage converter website: http://www.adequate-energy.co.za/DC_Purchase.htm

In particular, we are interested in the part AE-DC15-84.15A.12. You can see the spec sheet at: http://www.adequate-energy.co.za/images/AEDCCon12V15A.pdf

Unfortunately, you cannot just order it online, it appears as though you need to email their sales department at the following address: info@adequate-energy.co.za

Don't worry, it doesn't seem that there are high-volume purchase requirements, they quote the price at $96 for between 1-10 items. Even though the company does not appear to have a branch in the United States, they seem very to international sales. From the website: "We are currently building a international dealer network for our DC-DC converters. If Adequate Energy is not yet represented in your country, Adequate Energy will airpost your DC-DC converter (arrival within 4 - 10 business days) at no extra charge for orders of under 10."

Do we need info on 36V to 24V converters for the SICK laser as well?
